feat(web): video player i18n

[meesfrensel]

Description

Follow-up PR to the custom video player. This is not the solution we wanted, but the media-chrome team is not interested in weblate or adding many languages in one go (see muxinc/media-chromenumber#1290), so adding the strings to our own weblate translations is an alternative solution.

I copied over the existing translations they have upstream.

Upsides of the specific implementation of spreading ...En (the english strings) and then overriding some of them:

• We only translate the strings that we need
• If new strings are added upstream, we don't get type errors (because those new keys are missing from the object)

Downsides:

• If new strings are added upstream, we won't know unless we actively check all releases for this, or get a report of missing translations after an Immich release.

How Has This Been Tested?

Change to all these languages, and another one (fallback remains english)

• Check strings are translated
• Check strings fit within their containers (needed to change the settings menu to min-w to fit long German words)

English	German
